摘要： A system includes a self-backhauled eNodeB which communicates via a radio interface with an anchor eNodeB, where the self-backhauled eNodeB is made reachable in an operator's network via a serving gateway and where the serving gateway of the self-backhauled eNodeB owns an IP address associated with the self-backhauled eNodeB. The system receives a packet destined for the self-backhauled eNodeB and classifies the packet to a bearer associated with a self-backhauled link to the self-backhauled eNodeB.

摘要： A multihop network and nodes are described herein that implement a reactive routing protocol that enables resources of the multihop network to be continuously adapted in a distributed/opportunistic manner in response to a topology change within the multihop network so as to optimize the performance of a connection between a source node and a destination node. The types of resources that can be adapted include for example: (1) a route; (2) a channel; and/or (3) physical layer parameters. The different types of topology changes that can occur include: (1) movement of a node; (2) quality variations in a channel between the source node and the destination node; (3) changes in traffic patterns in the multihop network; (4) changes in transmit patterns (e.g., power, beamforming direction) in the multihop network; and (5) changes in resource allocations in the multihop network.

摘要： The present disclosure discloses a method in a wireless access network node for controlling a UE. The UE comprises at least two transmit antennas, and is capable of uplink transmit diversity. There is an antenna weight associated with each transmit antenna. First, the wireless access network node determines that the antenna weights of the user equipment may be controlled. Then, it creates a control signal that comprises control information and transmits it to the user equipment. The control information controls a UE autonomous selection of the antenna weights in the UE.

摘要： The network node of a cellular network assigns a first part of a shared radio resource to a first User Equipment, UE, for uplink transmissions in the cell, and instructs the first UE to apply a first UE-specific Hybrid Automatic Repeat Request, HARQ, process for transmitting on the assigned first part. The network node also assigns a second part of the shared radio resource to a second UE for uplink transmissions in the cell, and instructs the second UE to apply a second UE-specific HARQ process for transmitting on the assigned second part, the second HARQ process being separate from the first HARQ process. The network node then receives data transmitted from the first UE on the assigned first part based on the first HARQ process and data transmitted from the second UE on the assigned second part based on the second HARQ process.

摘要： Techniques for the secure generation of a set of encryption keys to be used for communication between a wireless terminal and an assisting base station in a dual-connectivity scenario. An example method includes generating (810) an assisting security key for the assisting base station, based on an anchor base station key. The generated assisting security key is sent (820) to the assisting base station, for use by the assisting base station in encrypting data traffic sent to the wireless terminal or in generating one or more additional assisting security keys for encrypting data traffic sent to the wireless terminal while the wireless terminal is dually connected to the anchor base station and the assisting base station. The anchor base station key, or a key derived from the anchor base station key, is used (830) for encrypting data sent to the wireless terminal by the anchor base station.

摘要： A NodeB (105) for an HSPA enabled WCDMA network (100), arranged (11, 12, 13) to transmit beam forming instructions to a User Equipment, a UE (110), which is arranged for beam forming. The beam forming instructions comprise information identifying a code book with one or more code words, and the NodeB is also arranged to transmit code words from said code book to the UE at a certain rate.

摘要： There is provided method and devices for handling multi path routing of data packets. The method comprises the step S1 of establishing a multi path connection with a target network node, the multi path connection comprising a plurality of paths over which data packets can be transmitted to the target network node. The method also comprises the step S2 of obtaining information relating to the quality of the plurality of paths and the step S3 of determining, based on the obtained information, whether a path in the plurality of paths has been disconnected or is about to be disconnected. The method also comprises the step S4 of activating at least one substitution path if it is determined that a path in the plurality of paths have been disconnected or is about to be disconnected, to enable transmission of data packets intended to be transmitted on the disconnected path, or the path about to be disconnected, over the activated substitution path. Corresponding devices and computer programs enabling handling of multi path connections are also provided.
